📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

In previous years, the rangers said they try to get to the park and open the gate by 7:45 AM. From the website: [https://www.nps.gov/keaq/index.htm](https://www.nps.gov/keaq/index.htm) Waterlilies are bountiful all over the park! Our volunteers moved the tropical lilies from the hothouses to the display ponds, and they are vibrant. Bird enthusiasts have been enjoying watching the 3 young fledgling red-shouldered hawks, nesting orchard orioles, and kingbirds. Turtles have been laying eggs, and tadpoles and frogs are abundant in the ponds. Every year, we visit Kenilworth Aquatic Gardens on July 4th. The lotus flowers start blooming in early June and will be plentiful by the end of the month. The best time to visit is in the morning, as the temperatures are cooler and the flowers close up in the heat of the day, usually around 1:30 pm. I know it is outside of the Virginia Beltway, but it is not far. It is a very unique place in Washington, DC. I will be there in my grey pickup and rain or shine (hopefully shine)! Bring: Tripod Comfortable shoes Water Fully charged batteries Empty memory cards Rain poncho and plastic bags for the camera and lens in case of rain. Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos. Park Facts Entrance Fee: Free Allow Dogs with lease: No Bathroom: Restroom in the Visitor Center Address: 1550 Anacostia Ave, NE, Washington D.C. 20019 Lat, Long: 38.913003, -76.940142 - Parking Lot Plus Code: W375+6W Washington, District of Columbia Website: https://www.nps.gov/keaq/index.htm I generally schedule this meetup on the Fourth of July, as I would have the day off. They are open on July 4th, but one year we waited until 9:00 AM until a ranger showed up to unlock the gate, and it wasn’t a holiday. I also want to mention security, as in the past, a photographer in my group was at the gardens and saw someone’s car being broken into in the parking lot. From the parking lot, walk towards the gardens down the path. I usually stay to the left and head into the lotus fields. Please be careful, as there are just dirt paths between the fields, and if there has been a lot of rain, there can be ruts, and I almost twisted my ankle. You actually need a fairly long lens, as the lotus flowers are tall and can be some distance away. A wide angle is only good for some overall shots, and a good-sized macro works as well. Another thing folks do not realize is that the flowers do bloom into September, but have many full blooms. This is one park where you do not have to worry about mosquitoes, as they are eaten by pond beetles, dragonflies, and damselfly larvae, and also by frogs and birds. There is a boardwalk at the back of the flower fields that goes out to a marsh area. I have seen many types of birds and dragonflies in that area. Being there makes it hard to believe that you are in Washington, DC. On the way out, allow some time to check out the small ponds with different lotus and lilies that also attract frogs and dragonflies. Why you will not see any mosquitoes in the park: https://www.nps.gov/keaq/learn/nature/insects.htm By sending in an RSVP and joining this meetup event hosted by the Virginia Beltway Photography Meetup, I am also agreeing to the terms of the following release and waiver of liability, which shall be binding on my heirs, executors, administrators, successors, and assigns.

Socrates Café meets twice a month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian

Similar to our "Beginner Ride", a casual, on-road-avoiding, cycle-path-winding, beginner friendly, group ride. The ride will be led by Maya and Angie, who have a combined 50 years of cycling experience. This is a no drop ride with an average speed of 7- 12 mph. Please bring a helmet, lights, a snack, hydration and wear appropriate clothing for cooler weather (cotton is not your friend in cooler temps and we will be riding in the dark). The ride can be tailored to the skills that attendees want to master, i.e- drinking from water bottle while riding, making tight turns, riding in a small group and cycling etiquette. We will be riding mainly on trails, streets as minimally as possible, and sidewalks only when necessary. This ride is perfect for someone who hasn't ridden in a while and wants to get some easy miles on the saddle; not just for newbies. If you have not ridden your bike in several weeks, months or years, please have a safety check done before the day of the ride. We are just here to have fun.

Join us for a discussion of ***The Anthropocene Reviewed: Essays on a Human-Centered Planet* by John Green.** Here's the summary: The Anthropocene is the current geological age, in which human activity has profoundly shaped the planet and its biodiversity. In this remarkable symphony of essays adapted and expanded from his ground-breaking, critically acclaimed podcast, John Green reviews different facets of the human-centered planet - from the QWERTY keyboard and Halley's Comet to Penguins of Madagascar - on a five-star scale. Complex and rich with detail, the Anthropocene's reviews have been praised as 'observations that double as exercises in memoiristic empathy', with over 10 million lifetime downloads. John Green's gift for storytelling shines throughout this artfully curated collection about the shared human experience; it includes beloved essays along with six all-new pieces exclusive to the book. **Let’s meet at Caboose Commons in Fairfax to enjoy some good discussion and meet new friends.**

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability.

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is sponsored the Dianetics & Scientology Self-Improvement Center.

You can sleep in on the Semiquincentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
